During a trip to Berlin, a young Amish in the middle of a rite of passage reconnects with his roots, explores other ways of life, falls in love — and faces a big decision.
This is the third and final part of the now famously successful trilogy, where Mr. Müller and his problem kids Chantal, Danger and Co. once again take up arms against their sworn enemy, the German education system.
Isi doesn't get the world anymore. Just a short while ago, life was wild, fun, and without obligations, but suddenly everyone around her seems to be grown-up and successful. With her diploma in one hand and a drink in the other, she is stuck between the careless days of college and real life. When her best friend Lotte gets a respectable job and becomes pregnant, Isi realizes that she needs to find a way to start living a life on her own.
Mr. Müller is not satisfied with his new work at the Goethe-Gesamtschule. The early getting up and correcting exams annoy him. Director Gerster wants to improve the image of the Goethe-Gesamtschule because she wants to be a symbol of the new company. To achieve this, she wants to take away the partnership from the Schillergymnasium with a Thai school. So, Mr. Müller, Mrs. Schnabelstedt and the 10b must go on a school trip to Thailand.
